“…The NDSI threshold is the most important factor affecting the result accuracy. Based on the previous results [7] , through repeated tests and combined with the actual situation of Urumqi Glacier No.1 and visual interpretation results, it is believed that the NDSI threshold of 0.75 ~ 0.96 is suitable for area.…”

In mid-latitude glaciers, the altitude of the snowline at the end of the ablating season can be used to indicate the equilibrium line, which can be used as an approximation for it. In this paper, Urumqi Glacier No.1 was selected as the experimental area while Landsat TM/ETM+/OLI images were used to analyze and compare the accuracy as well as applicability of the visual interpretation, Normalized Difference Snow Index, single-band threshold and albedo remote sensing inversion methods for the extraction of the firn lines. The results show that the visual interpretation and the albedo remote sensing inversion methods have strong adaptability, alonger with the high accuracy of the extracted firn line while it is followed by the Normalized Difference Snow Index and the single-band threshold methods. In the year with extremely negative mass balance, the altitude deviation of the firn line extracted by different methods is increased. Except for the years with extremely negative mass balance, the altitude of the firn line at the end of the ablating season has a good indication for the altitude of the balance line.

“…For instance, in the Normalized Difference Snow Index (NDSI). With the threshold value of 0.57≤NDSI≤0.72 is set to identify the range of snow cover [7]. The third one is the single-band threshold method where the gray threshold value of 90~160 in the Thematic Mapper(TM)4 band is set to extract the snow cover range [8].…”

“…Some of the advantages include low cost, high efficiency, minimization of sludge production, possibility of regeneration of biosorbent and metal recovery [7,9]. Biosorption is therefore seen as an alternative method that can be categorized as a green technology for heavy metal removal from industrial effluents [10]. Different parts of plants and their related wastes are naturally available as well as inexpensive in comparison to other chemically modified materials.…”

In this research Curcuma longa Rhizome, an agricultural product, available in large quantity in northern Nigeria, were used as low-cost adsorbent for removal of Pb(II) and Ni(II) ions from aqueous medium. Batch operation was used to study the equilibrium behaviour of Curcuma longa rhizome. The effect of solution pH, and contact time on the adsorbent for the removal of Pb(II) and Ni(II) ions were evaluated. To study the adsorption kinetics of Pb(II) and Ni(II) ions onto Curcuma longa Rhizome, pseudo-first-order, pseudo-second-order as well as three diffusion models: intraparticle diffusion model (Weber and Morris model), film diffusion model (McKay model) and liquid film Models were used. The sorption kinetics can be described well by the pseudo-second-order model due to the closeness between the qexp ( 49.26 mg/g) and qcal (52.63 mg/g) for Pb(II) and qexp (57.60) and qcal (55.56 mg/g) for Ni(II) ions. Moreover, the rate limiting step are liquid film and intraparticle diffusion controlled. In addition, the results suggest that Curcuma longa Rhizomes are very effective adsorbent for the removal of Pb(II) and Ni(II) ions from aqueous medium. This will serve as an indicator to consider in the design for waste water treatment plant for heavy metal detoxification using Curcuma longa Rhizome.

The work presented here is part of an overall design system with a silicon based ponent for the determination of copper, zinc. Voltammetric (the measurement tion of potential) methods of analysis are attractive for determinations of trace metals. They offer a combination of simple low cost instrumentation with excellent sensitivity and detection limits, comparable to those obtainable with instruments costing orders of magnitude greater. The system consists of (ASIC) and software control. There is increasing pressure on industry and regulatory bodies to monitor industrial and domestic pollution. A particular concern is the c o n~i n a t i o n of water supplies with heavy metals. The aim of this work is to develop a method of heavy s using a device that can be manufactured at are compatible with microelectronics processes giving a low cost solution to trace metal analyses for water quality applications. been designed with areas ranging from 0.2 mm2 to 3.75 mm2 compatible with reproducible area screen printing.electrodes, an application specific integrated circuit ASILTH Figure I : System Overview.The elements of the measurement system are illustrated in Figure 1. It comprises a disposable "Dipstick" rporating a sensor ASIC (ASICTH), a "System ' incorporating a measurement ASIC (ASICM), and a notebook PC AT compatible. The system is operated by connecting a "dipstick" to the "System Pod" and ing a drop of the analyte to be analysed to the tick". The presence of the sample is sensed and the starts a~~omatical~y. Electrodes have been fabricated by combining silicon fabrica~on and screen printing technologies. Platinum is deposited and patterned on a thermally oxidised silicon substrate. Titanium is used as an adhesion layer between the p~a t~u m and the oxide. A three electrode system is then realised by screen printing carbon onto two of the platinum electrodes to form the working and counter es. Silver/silver chloride (Ag/AgCI) is screen printed onto the third area of platinum to form a reference electrode. Both disc and band electrodes have Figure 2: Prototype design of electrodes made by screen-printing carbon and SilverlSilver Chloride inks onto a silicon wafer . 948 TRANSDUCERS '95 .
